This paper studies an optical wireless power transfer (OWPT) system, in which the transmitter is a set of LEDs belonging to a plane and the receiver is a small solar panel assumed to move within another plane that is not parallel with the transmitter plane. Owing to the nonlinearity and non-convexity of the DC gain of the OWPT efficiency from each LED to the solar panel, the transmission efficiency of the overall OWPT system is also a nonlinear and non-convex function of the transmitting distances. It is therefore challenging to determine the optimal relative position between the LEDs and the solar panel such that the OWPT efficiency of the whole system is maximal. Some initial results on this problem will be presented in current research with simulations and demonstrated with realistic experiments.
